无法打开，只要一启动变出现意外退出，
打开
~/Library/Containers/QReader.MarginStudyMac/Data/Library/Preferences
~/Library/Containers/QReader.MarginStudyMac/Data/Library/SyncedPreferences
这两个目录下，
删掉“QReader.MarginStudyMac.plist”这个文件。App应该能启动起来
这两个文件都删掉了，还是显示刚才的问题，意外退出，打不开
断开网能进吗?重启下mac呢？将此信息发给我们吧，看看什么问题，您也可以尝试卸载app后重新安装，不会清除数据的
一开始APP也卸载后重新安装了，断网的情况下也尝试了还是打不开 
能发一下文字版的吗，就是复制粘贴一下

又试了一次，重新下载后可以打开了，但是之前的部分笔记丢失了，请问可以怎么补救呢？
你是全部删除了吗？iCloud有吗？
没有手动删除，就是在卸载的时候可能给清理了，iCloud没有
Users/你的用户名/Library/Containers/QReader.MarginStudyMac/Data/Library/Application Support/QReader.MarginNoteMac里的这四个文档及文件夹：
嗯嗯，然后呢？
这些是你的笔记，你看看有多大？将它移入现在的MarginNote位置呢？
不是的，那就是正常的位置，你的笔记从这里看是不是少了呢？
今天手贱升级11系统，也遇见这个问题了，你们处理完成了吗
Hello
您好，请参考以上方法呢～
